New
Your stake and evidence for BA
What it means for you
This public view does not read your holdings or watchlist; open the member view to check your stake.
Use this to decide what to research, rather than as an instruction to copy a trade.
What happened
A position newly appears in the Q2 2026 book.
Displayed change: +$173.2M. The current book reports 800,000 shares.
Why it can matter
A change between quarter-end disclosures can prompt a question about the manager's exposure. It does not reveal the trade date, the execution price or why the position changed; a full exit is not proof of a bearish decision.
How we got this
A new position uses its current quarter's reported dollar value; this is not the amount spent buying it.
Comparable books exclude identified CUSIP, share-basis and new-security events from trades. Exit-size bands describe prior book weight, not the manager's intent.

Use this to decide what to research, rather than as an instruction to copy a trade.
What happened
Reported shares increased between Q1 2026 and Q2 2026.

Why it can matter
A change between quarter-end disclosures can prompt a question about the manager's exposure. It does not reveal the trade date, the execution price or why the position changed; a full exit is not proof of a bearish decision.
How we got this
